Detailed explanation-1: -In the gametophyte phase, which is haploid (having a single set of chromosomes), male and female organs (gametangia) develop and produce eggs and sperm (gametes) through simple mitosis for sexual reproduction.

Detailed explanation-2: -However, mitotic division still follows meiosis in the sporophyte, resulting in a multicellular gametophyte, which produces eggs or sperm. All of this takes place in the the organ that characterizes the angiosperms: the flower.

Detailed explanation-3: -The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively. Collectively these structures are known as gametangia.

Detailed explanation-4: -The primary job of gametophyte is the production of Gametes. The produced gametes are the haploid reproductive cells, such as sperm and eggs.

Detailed explanation-5: -Gametophytes are the stage which produces sex cells in plants and algae that undergo alternation of generations. Among land plants, these sex cells may be referred to as “sperm” and “eggs, ” with “male” and “female” sex cells combining to produce offspring.
